Gertie moves around by leaning in a certain direction, and then jumping! It\’s outside is made out of silicone so it squashes and stretches as he moves. It\’s internal mechanism is a delta robot controlled by a on-board Raspberry pi. The servos have what is called \’series elastic actuator\’ which is just a fancy term for the motors use springs to collect all of that potential energy of the first jump, and jump even higher on the second jump like a pogo stick! rnrnAs a side project so have kids would have something fun to do, I build larger versions of Gertie and equipped it with the fastest servos I owned just to see how high they could jump! The jumping is controlled through a hacked staples \’EASY button\’ that put an arduino pro mini inside, along with a wireless NRF24L01 so that it can make the robot jump wirelessly. I also replaced the red part of the button that said\’EASY\’ with a 3D printed replacement that says \’JUMP\’on it. I\’m uploading the blank button to Thingiverse so that other people can print it out as well.rn”,”public_description”:”Gertie is an egg-like robot that moves around by jumping!
